BUTTON -FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 336,943, dated March 2,1886.

Application filed December 21,1885. Serial No. 186,314. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE W. PRENTICE, a citizen ofthe UnitedStates,residing at Providence, in the county of Providence and State ofRhode Island, have invented certain new and useful Improvements inStaple Fasteners; and I do declare the following to be a full, clear,and exact-description of the invention,such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to the letters andfigures of reference marked thereon, which form a part of thisspecification.

This invention relates to that class ofbuttonfasteners styled staples,heretofore made by cutting and bending a strip of wire into a loophaving two depending legs, which are passed through the material towhich the button is to be secured, and clinched. The object of thisinvention is to produce a stronger and more effective staple fastenerfor eye-buttons; and it consists of a staple made from a blank cut fromsheet metal, having three legs or projections, which is bent at or nearthe center of its length, parallel with each other, all as will behereinafter more fully described.

Figures 1 and 2 are perspective views of my improved staple fastener;Fig. 3, a planview of the blank from which the staple is made.

The staple A is cut from sheet metal into form substantially like thatshown in Fig. 3; and it consists of the single leg at, and the doublelegs b b. The sides of the blank A are cut in obl1que lines from thepoint of the leg a to the ends of the legs bb, and the metal betweensaid double legs is cut out on the line from the ends of the same inwardto the center of the blank. The blank is then bent at or near itscenter, bringing the prongs parallel with each other, and thus formingthe loop a, for the reception of the eye of a button, as fully shown inthe drawings.

The loop 0 may be formed roundedas shown in Fig.1, or angular, as inFig. 2, the former being better adapted for fabrics requiring along-eyed button, as the eye of the button is drawn down closer to thefabric when secured thereto than with the angular loop, as the crown ofthe latter stands higher above the fabric, allowing a shorteyed buttonto be employed. I

In securing a button to fabric by means of my improved staple abutton-eye is passed over the leg a into the loop 0, and the legs areall passed through the fabric and clinched, the material between thedouble legs being compressed into the wedge-shape space, forming abearing on the surface for that portion of the staple. The sides of theblank being cut on oblique lines allows a great variation of-the shapeand dimensions of the loop desired to be made.

Having described my invention, I claim 1. The triangular blank A,comprising the legs a and b b, the latter being cut in oblique linesfrom the point of the former, the spacebetween the legs I) I) being cutin oblique lines to a point at or nearthe center of said blank,substantially as and for the purpose specified.

2. The herein-described sheet-metal staple, provided with the divergenttapered legs a and b b, the leg (1. being bent parallel to the legs b b,forming the loop 0, adapted to engage the eye of a button, all the saidlegs to be passed through the material and be subsequently clinched,substantially as specified.

In testimony whereof I affix my signature in the presence of twowitnesses.

GEORGE W. PRENTIOE.
